Hello,

I'm having one of the same problems as mic_q and wondered if anyone had any ideas on a solution.

The TV is about two years old at this point and has already had a lamp replacement. When the lamp was going out the TV would turn off and then not come back on until days later.

Now when turning on the unit, it will turn itself off after a couple of minutes. Turning it back on will give another few minutes of view time before it turns off again. Usually this will happen 2 - 4 times before the TV will finally stay on permanently, usually for hours.

The lamp is only a few months old, so it doesn't seem like that should be the problem, plus it works fine once it goes through the cycle of shutting off a few times at the beginning.

Any idea what this could be?

Thanks.

marvelgoalie: As far as the white dots I found another post saying it was possibly a board (DMB I think?) However, after speaking with a service tech who's been out on my 5075s 4 times, I'd say start with the lamp first. He showed my my lamp when I had him out trying to fix my ongoing problem and explained that the initial startup of the lamp can cause arcs that damage the bulb then produce all sorts of little dust flecks inside the lamp itself. Thats why frequent power cycling isn't recommended.

I wanted to drop by the post to say goodbye to my 5075s. I've very much enjoyed it since we got it despite the tuner issue...I've not so much enjoyed my experience with Samsung support trying to get it resolved...but it looks like in about a week it will be replaced free of charge with a LN46B550. Not happy about losing 4 inches but I suppose its what I can get. (Check my userprofile for homepage, then click "samsung" tag if you care for that read)

I looked in the Menu under Channel list and it looks the tv doesn't even scan that range. The channel menu has 116-10 and then skips all the way up to 124-1. Anyone know why it does that? Anyone know if there is a firmware flash for the set that may correct this?

Ah, my buddy also said that his Sony wont get 117-1. He said he only gets 117-1 on his Hauppauge tv tuner card on his pc.

Anyone have any insight on this issue?

Sorry for the massive delay on this reply, but I figured I would attempt to answer: Signal strength based on the tuner perhaps, or perhaps its related to the ongoing problem of the bad tuner firmware in the set that I've tried to get fixed the past two years. The tuner is flaky.

I have a 2+ year old 50 inch DLP model, and in the last two weeks, at very random times, the volume has shot all the way up to 100 and then freezes. Had to unplug the tv to turn it off, and then plugging it back in seemed to fix things (although I had to do that twice the last time this happened to fix it.) Even when I had the volume down to 0, as I was using my surround speakers, it suddenly shot up to 100.

One other point (may or not be related)
On occasion since I have owned it, the TV would not turn off when I pressed power, but rather would make a screeching noise and turns itself on and off and then stay on. After which, I could just turn it off, so I have basically ignored that problem. Figured I would mention now in case it is connected to the volume thing.

Not sure if anyone is still reading this thread, but if you are, I posted a note about how my HLT unit is suddenly having the volume shoot to 100 and then locking up. This weekend it did it a few more times, and then suddenly shot into the display menu and was blinking back and forth. It was as if someone was holding the remote buttons down to keep bouncing into different menus. But I had already taken the batteries out of the remote in case a button was stuck or something, so I don't know what the cause is.

Any ideas? Or anywhere else on the forum to post this?

A friend of mine is having a problem with his 5075S. When he first goes to turn on the TV in the morning it will attempt to turn on but then shuts off. After that 1st attempt it will then turn on as normal. He just had the bulb replaced a few months ago and the blinking light indicates an overheating problem but the TV couldn't be overheated because it's been off overnight. It's always the same, 1 cycle and then it's fine. Any ideas before he has to put in a service call.

Got the same email and like you, don't know what the 'shadow effect' they are referring to.

I know this is an old thread but Samsung is still servicing out of warranty TV's of this model and want to share my experience.

I have model # HL-T5675s that I've owned since Nov 07 and last week have been developing white and black dots all over the screen. Called 1800 samsung and they are sending a tech out for a free one time repair to swap out the DMD chip. This will be my first problem with this set since I've bought it. We'll see how it goes.

Buzzam - How did the service from Samsung go? Did they tell you that you will have to pay for labor?
